My ABS dash light recently came on in my 2009 BMW 328XI and I have concluded that I need to buy a code reader for BMW vehicles. I've never purchased one of these before, so I have no idea what I'm doing. Should I get one that's made specifically for BMWs or do they make ones that can be used for all different types of cars? What are the good brands? Are some better than the others? From what people are saying in my original post, one of my ABS wheel speed sensors may have gone bad or may be malfunctioning. I need to know, first, if this really is the problem and second, if it is, which wheel speed sensor has gone bad. I watched a few videos on YouTube and have read the responses to my post and from what I gather, only some code readers will tell you which sensor is malfunctioning while the car is sitting still. With others, the car will need to be driving. I would rather have my car parked and idling while I'm testing the system, so that's the kind of code reader I want to get. Any advice would be appreciated.
